Solar Energy - Wikipedia, the Free Encyclopedia
Solar energy - Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/Solar_energy From Wikipedia, the free encyclopedia Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar energy technologies include solar heating, solar photovoltaics, solar thermal electricity and solar architecture, which can make considerable contributions to solving some of the most urgent problems the world now faces.[1] Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy. Passive solar Nellis Solar Power Plant in the United States, one of techniques include orienting a building to the Sun, selecting the largest photovoltaic power plants in North materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air. America. In 2011, the International Energy Agency said that "the development of affordable, Renewable energy inexhaustible and clean solar energy technologies will have huge longer-term benefits. It will increase countries’ energy security through reliance on an indigenous, inexhaustible and mostly import-independent resource, enhance sustainability, reduce pollution, lower the costs of mitigating climate change, and keep fossil fuel prices lower than otherwise.

As affordability of solar energy in buildings, namely, hybrid solar we entered the century, the sun was our primary source of lighting and full-spectrum solar energy systems. By using interior light during the day. Eventually, however, the cost and different portions of the solar spectrum simultaneously for performance of electric lamps improved, and the sun was multiple end-use applications in buildings, the proposed system displaced as our primary method of lighting building interiors. -

Clean and Green Technology : Hybrid Solar Lighting
Clean and Green Technology ‘Hybrid Solar Lighting’ Abstract— We demonstrate an innovative application and turned off during the day, which results in lower electricity investigative results of fiber optic day lighting systems as a bills and less energy demand. means of bringing direct sunlight into a building while maintaining the controllability and ease of application usually reserved for electric lighting by collecting natural light and channeling it through optical fibers to luminaries within the space. In contrast to conventional methods of lighting as well as solar energy, this project focuses on reducing losses due to radiation, transmission and conversion to achieve increased efficiency and provide a profitable solution to the energy crisis the world is facing today. This project manifests the system performance which is accurately described by employing and analysis based on fiber and lens optics and interior illumination. Excellent efficiency is achieved which is only slightly reduced due to either transmission losses, although negligible, or a cloudy day, by employing the concept of hybridizing solar source along with electrical source for optimum interior lighting. This is implemented by using high quality Fresnel lenses (for concentrating and collecting sunlight), optical fibers (for transmission) and luminaries (for lighting). Large scale commercial buildings such as textile showrooms, malls, hospitals, museums, schools, colleges are the major nerve centers of applicability of this project. For Figure 1: Principle of HSL employing simple yet innovative principle, elementary mechanical concepts were executed with the sole purpose of curbing pollution, to dwindle green house effect and tackle energy crises. The high efficiency ingenious applicability III. MATERIALS REQUIRED achieved in this project brings it one step closer to commercialization. -
